摘要： [Problem] Provided is a bipolar secondary battery capable of avoiding a flow of a short-circuit current through the secondary battery via current collecting plates if an electrical conductor penetrates an exterior body.
[Solution] The bipolar secondary battery includes a power generation element 10 including unit power generation elements 14b stacked together and including bipolar electrodes 14a stacked via separators 15, and current collecting plates 16 and 17 arranged at both ends of the power generation element 10 in the stacked direction of the unit power generation elements 14b so as to be in contact with the power generation element 10, wherein the current collecting plates 16 and 17 each include an electrically conductive layer 31 and a resin film, the electrically conductive layer being formed on the resin film 30 having a thermal shrinkage percentage of 2% or greater at a temperature of 150°C, and the separators 15 have a higher thermal shrinkage start temperature than the resin films 30.

摘要： An object of the present invention is to provide a means for improving output characteristics at a high rate in a non-aqueous electrolyte secondary battery including a thickened positive electrode active material layer.
A positive electrode for non-aqueous electrolyte secondary battery according to the present invention has a positive electrode active material layer having a thickness of 150 to 1500 µm formed on a surface of a current collector. In addition, the positive electrode active material layer includes coated positive electrode active material particles in which at least a part of a surface of a positive electrode active material is coated with a coating agent containing a coating resin and a conductive aid. Furthermore, a porosity of the positive electrode active material layer is 35.0% to 50.0% and a density of the positive electrode active material layer is 2.10 to 3.00 g/cm 3 .
